Abstract
To evaluate the shear strength of RC bridge piers, comparison of analytical results using modified compression field theory and experimental results which applied the horizontal load to the real RC column and 1/3 scale large specimens, was performed. The analytical results coincides relatively well with the experimental results, and it is also shown that the concrete shear strength reduces after main reinforcing bars reaches the yield strength. The parametric studies show that the increase in hoop ties leads to high crack inclination and then 45° -truss analogy over-estimates the shear resistance carried by hoop ties.
